PTKM25R-40SM

Fixed Inductors

Fixed inductors are electronic components used in electrical and electronic circuits. They are also called chokes, coils or reactors, depending on their application. The PTKM25R-40SM is a fixed inductor that is widely circulated in the market.

Application Field

The PTKM25R-40SM is popularly used in low-frequency power circuits and filters. This inductor also plays an important role in controlling the current and voltage in an AC oscillator. It also helps in managing the circuit power, especially in the case of rectifier output circuitry. This inductor is also used in power switching regulators, resonant circuits, LED drivers and LED ballast circuits, among others.

Working Principle

The working principle of the PTKM25R-40SM is based on Faraday’s law of induction. When a changing electric current passes through a coil, it creates a magnetic flux in the coil. This magnetic flux passes through the core and induces current in the other winding of the coil. This induced current creates a changing magnetic flux, which again passes through the core and induces current in the first winding of the coil. This process of creating changing magnetic flux in each winding occurs repeatedly to produce an inductor. With the help of the PTKM25R-40SM, the generated magnetic flux and the charges flowing in these windings produce forces that oppose the change of current. This inductor then helps in controlling the current and voltage in the circuit.

The PTKM25R-40SM has many advantages due to its design. It has a compact size and can be used for various applications. It also has a relatively low cost compared to other types of inductors. It is also easy to use and install and does not require additional components. Moreover, it is highly reliable and works in a wide range of operating temperatures.

In conclusion, the PTKM25R-40SM is a fixed inductor with many advantages. It is widely used in low-frequency power circuits and filters. It is also used in other applications and works through Faraday’s law of induction. The inductor creates a magnetic flux in the windings and this induces current in the other winding. This process helps in controlling the current and voltage in the circuit.
